It can go spoil and become rancid.
Not for very long at room temperature- you should eat it soon after you put in on whatever it goes on to. In the refrigerator it keeps over night somewhat satisfactorily- you can rewhip it and sometimes help it. By the third day it is quite liquid,but still tastes good.
Fresh whipped cream typically lasts for about 2-3 days in the refrigerator before it spoils.
it would only last a day if you put it in the fridge
It depends, if you are referring to the pastry cream/whipped cream mixture piped inside the choux paste, or something else. If you're making eclairs or cream puffs, they should last a few days in the fridge.
In my younger days I used to drink it with chocolate milk and whipped cream on top. Too bad they don't make it without alcohol. :(
you store it in a plastic, glass or ceramic bowl with plastic cling wrap sealing the air out, then put it in the fridge. it should be used within 3 days of being whipped, depending on when the cream was initially bought.
It will smell sour and could be clotted or curdled.
Since cream cheese is made out of fresh cream I would treat it like milk. How long do you let your milk go without refrigeration?
If you put it on right after you get it out of the oven, it will flop over and go all over the cake, so it's best to wait right before you serve it to put the whipped cream on. or wait till you cut it, then put the cream on, and then you can easily add more if necessary.
If stored properly in the refrigerator, it can last for a week or two.
As with any cooked foods, it should never be left at room temperature longer than 2 hours.
